About this site
Privacy Information
What happens when you use the site and its tools.
This website serves informational pages, product images and planning tools. It does not offer user accounts, a checkout, a newsletter signup or a comments system in this build. Please do not send passwords, payment details or private documents through any site-related communication.
Calculators and browsing
The finder and calculators process the values you enter in your browser. Their code does not send those form entries to our server, store them in browser storage or create a user profile. The finder downloads the public product catalog to display its suggestions.
Hosting infrastructure processes requests needed to deliver the website and may maintain operational or security logs. We do not promise that browsing creates no records. The hosting provider’s handling of requests is separate from the local calculations performed by the tools.
Third-party requests
Product images are loaded from third-party image servers. Those servers receive normal web request information when an image is requested. Following an Amazon link takes you to Amazon, where its own privacy and cookie practices apply. Manufacturer documentation links similarly take you to independent websites.
Affiliate links contain a tracking identifier used to attribute eligible purchases. This website does not receive your Amazon password, payment card details or full order information merely because you follow such a link.
Changes to this site
If accounts, analytics, forms or other data collection features are added later, this page should be updated to explain them before those features are used. For editorial issues, consult the contact page. For our affiliate relationships, see the disclosure.
